IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent N 0. 186,101, dated January9, 1877; application filed November 11, 1875.

To all whom it may concern Be it known that I, JOSEPH BENsoN, of Boston,in the county of Suffolk and State of Massachusetts, have invented newand useful Improvements in Vapor-Lamps, of which the following is aspecification:

My invention relates to certain improvements in lamps; and consists incombining with the wick-tube projections which lie over the wick at theend, and extend below and onter the wick-tube, as will hereinafter morefully appear.

In the accompanying plate of drawings, Figure l is a verticalcross-section of a vaporlamp constructed according to my invention. Fig.2 is a plan view, and Fig. 3 a horizontal cross-section, of wick-tube online .10 m, Fig. 1.

In the drawings, A represents the body of a vapor-lamp, and B thewick-tube, adapted, with a cap-plate, O, to be attached and removed asordinarily. This wick-tube B projects into the bodyA of the lamp, and itis filled and packed With granulated or pulverized mica and asbestus inequal parts or thereabout, as at D, which packing D is the wick of thelamp. a a, perforations or slits in the sides of that partE of thewick-tubeB which is within the lamp-body A. These perforations afi'ord afreer communication between the oil in lamp-body A and the wick D. b b,

projections which lie over the burning end F of the wick-tube, and fromthere they extend down the sides of the wick-tube B and enter the insideof the same, as shown at f, Fig. 1.

The wick, by means of the projections b and wick-tube, conducts heatfrom the flame to the oil in a most efficient manner, thereby greatlyincreasing the brilliancy and clearness of the illuminating flame. Ifthe wick-tube does not press close to the bottom 9 of the lamp-body,then the lower end h of the wick-tube should be closed preferably withwire-gauze or a perforated cap.

Instead of using mica and asbestus combined, as herein described, for awick-filling to the Wick-tube, mica, or asbestus alone may be used, butit is preferable to use the two together.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is-

.The projections b, overlaying the burning end of and also entering thewick-tube B, substantially as described, for the purpose set forth.

JOSEPH BENSON.
